Patented June 27, 1939 UNITED STATES SLUG CASTING MACHINE William B. Ankarstran, Astoria, N. Y., assignor to Mergenthaler Linotype Company, a corporation of New York Application April 20, 1938, Serial No. 203,079

15 Claims.

This invention relates to slug casting machines of the general organization represented in U. S. Letters Patent No. 436,532 to O. Mergenthaler, wherein a slug or type-bar is cast in a slotted mold against a composed line of matrices which produce the type characters thereon. In these machines, the molds are usually mounted in a vertical intermittently rotating carrier or disk which presents the slotted mold in a horizontal position for easting and thereafter carries it around to a vertical position in front of an ejector blade which pushes the cast slug from the mold. The mold disk is usually equipped with studs or pins which project from the face thereof and, during the slugcasting and slug-ejecting operations, are adapted to engage in recesses or sockets formed in a righthand and a left-hand locating block mounted on the vise frame. Ordinarily, the left-hand block is floatingly attached to the vise frame by two screws or bolts, while the right-hand block is fixed to the vise frame by screws or bolts and dowel pins. Due to wear, the locating blocks have to be replaced from time to time and much difficulty has been experienced in drilling a new right-hand block so that the dowel pins by which it, is fixed to the vise frame will be accurately centered with respect to the dowel holes already in the vise frame. I

The present invention is'directed to an improved form of locating block intended to obviate the foregoing and other difficulties, as will be fully described in the detailed description to follow.

In the accompanying drawing, the invention has been shown merely by way of example and in preferred form, but obviously many variations and modifications may be madetherein which will still be comprised within its spirit. It is to be understood, therefore, that the invention is not limited to any specific form or embodiment, except insofar as such limitations are specified in the appended claims.

Referring to the drawing:

Fig. 1 is a plan view, showing in section the mold disk and vise frame with the improved locating block; A 1

Fig. 2 is a side elevation, partly in section and partly broken away, showing the detail of the improved locating block; and,

Fig. 3 is a perspective view of the mold blockin disassembled condition.

As usual, the mold disk A, equipped with one or more molds A is mounted for .rotation upon the arm or support B projecting laterally from the mold slide (not'shown) which is arranged to be reciprocated forwardlyand backwardly in the machine frame. The disk A is power operated for intermittent rotation in such manner that during casting the slotted mold A is presented in a horizontal position and after casting carried around to a vertical position as shown in Fig. 1, where it registers with a pair of trimming knives C between which the slug is ejected from the mold by an ejector blade D. As is well known, the reriprocation of the mold slide is timed so as to move the disk A rearwardly when it is to hem rotated to carry the slotted mold from casting to ejecting position, or vice versa, and to move the disk forwardly when in either of such positions, in one case to insure the close contact of the mold with the composed matrix line and in the; other to locate the mold in immediate proximity to the trimming knives C. The mold disk is provided with diametrically opposed pins or studs A which, when it is moved forwardly, engage in corresponding sockets in the right and left locating blocks A such engagement effecting and maintaining the proper registration of the mold with the cooperating devices. Ordinarily, the lefthand locating block A is made in two pieces A and A secured to the vise frame E by screws A the arrangement being such that the shanksof the screws A fit snugly in the openings A in the portion A of the block while the openings A in the portion of the block A through which the screws A pass, are larger in diameter than the, shanks of the screws so that the section A is capable. of floating in a lateral direction to compensate for slight changes which take place in the distance between the pins A on the disk A as a result of expansion and contraction thereof. However, the right-hand locating block A heretofore has been made in one piece and fixed rigidly to the vise frame to locate the mold accurately with reference to the trimming knives C at all times.

According to the present invention, the righthand locating block A is made in two pieces A and A primarily for adapting it as a replacement block although obviously being as well adapted for original installation.

Referring particularly to Figs. 2 and 3, the portion A of the block A is adapted to serve as a base fixed to the vise frame E by dowel pins A the socket portion A of the block beingadapted to be mounted on the base A and detachably se-1 cured by screws A extending through the vise frame E and base A and being screwed into threaded openings A in the socket portion A In order to locate the socket portion A accurately to align with and receive the pins A on;

the mold disk, it is formed on its front face with a projection A adapted to seat in an opening A formed in the base A With this arrangement, when the socket portion A of the block A becomes worn, as frequently happens, it is merely necessary to replace this portion of the block, the base A which is fixed to the vise frame and which is not subject to wear, remaining in place to receive the replacement socket portion of the block. a

The socket portion A is formed also to serve as a templet for locating the base A on the vise frame E when the original installation of the base is made. To this end, the socket portion A is formed with two openings A and it, along with the base A is temporarily fastened to the vise frame E by the bolts A whereby the holes A serve as guides for drilling holes A in the base A and vise frame E for the reception of the dowel pins A It is pointed out that the socket portion A need only be formed with the openings A when it is to be used for the original installation of the improved form of locating block since, as a replacement element, only the socket portion A is required, the base A which has previously been fixed to the vise frame being unreplaced. I

Obviously, if desired, the invention might be applied in connection with the left-hand locating block A but here it is a matter of choice whether the base A of the block is fixed to the vise frame E because some floating of the block is desirable.

As already stated, variations and modifications of the invention may occur to those skilled in the art which will still be comprised within its spirit and, therefore, the invention is not limited to any specific form or embodiment, except insofar as such limitations are specified in the appended claims.
